Final answer:
To update the hiring criteria for entry-level engineers, a job analysis is required to determine the essential KSAs for the role using methods like observation, surveys, and interviews.
Step-by-step explanation:
The director of Human Resources realizes that the KSAs (Knowledge, Skills, and Abilities) currently used for hiring entry-level engineers are outdated. In order to establish which KSAs are needed, a job analysis is required. This process involves observing proficient employees, conducting surveys, and interviewing current job holders and their supervisors to understand the requirements of the position fully. A job analysis helps determine the tasks, knowledge, skills, abilities, and other characteristics that are necessary for successful job performance. Additionally, assembling this information is critical for creating accurate job descriptions and specifications that candidates' KSAs can be matched against during the hiring process.
